Eu estou correndo em um ConstraintViolationException quando tento salvar um objeto com um mapa @OneToMany nele. Hibernate quer parece pensar que eu estou tentando colocar um NULL na lista mapeada ou pode ser colocá-lo lá em si. O problema parece acontecer esporadicamente:. Com alguns bancos de dados é facilmente reprodutível, mas com os outros eu não posso fazê-lo acontecer em tudo
Eu sou uma espécie de novato, tanto Hibernate e Hibernate Annotations, portanto, qualquer ajuda em tudo seria muito apreciado.
Eu tenho duas classes: Camera e AlarmZone (que se estende a 3ª classe, Zone). Entre outras coisas, Camera contém uma lista de IDs de objetos AlarmZone. Eis as declarações de classe:
@Entity
@Inheritance(strategy = InheritanceType.JOINED)
@Table(name = "cameras")
public class Camera
{
private Serializable id;
private List<Serializable> alarm_zones = new ArrayList<Serializable>();
...
@Id(generate = GeneratorType.SEQUENCE)
@Type(type = "java.lang.Long")
public java.io.Serializable getId()
{
return this.id;
}
public void setId(java.io.Serializable id)
{
this.id = id;
}
@OneToMany(targetEntity = java.lang.Long.class, fetch = FetchType.EAGER)
@JoinTable(table = @Table(name = "cameraalarmzones"))
public List<Serializable> getAlarmZones()
{
return alarm_zones;
}
public void setAlarmZones(List<Serializable> alarm_zones)
{
this.alarm_zones = alarm_zones;
}
...
}
@Entity
@Inheritance(strategy = InheritanceType.JOINED)
@Table(name = "zones")
public class Zone
{
private Serializable id;
...
@Id(generate = GeneratorType.SEQUENCE)
@Type(type = "java.lang.Long")
public java.io.Serializable getId()
{
return this.id;
}
public void setId(java.io.Serializable id)
{
this.id = id;
}
}
@Entity
@Table(name = "alarmzones")
public class AlarmZone extends Zone
{
...
}
Sempre que eu salvar um objeto, eu uso o que eu entendo ser clichê comprometer código:
public Persistable makePersistent(Object entity)
{
try
{
Hibernate.getSession().beginTransaction();
Hibernate.getSession().saveOrUpdate(entity);
Hibernate.getSession().flush();
Hibernate.getSession().getTransaction().commit();
} catch (RuntimeException e)
{
Hibernate.getSession().getTransaction().rollback();
logger.error("makePersistent(" + entity.getClass().getSimpleName()
+ ")", e);
}
return entity;
}
O problema acontece quando eu salvar um AlarmZone, em seguida, colocar o seu ID em lista da câmera e tentar salvar a câmera. Para obter uma melhor informação de depuração, eu segui o conselho de https: //forum.hibernate .org / viewtopic.php? p = 2220295 & sid = a7ccc3be32137436c8062a99c8372a9e e definir o meu tamanho do lote a ser 0 e ligou nível DEBUG depuração em log4j. Aqui está o rastreamento de pilha para o erro (junto com os anteriores poucas linhas):

Solução
Há vários problemas com seu código:
- Você tem ids declarados como Serializable vez de
longsimples (ouLong). Por quê? - Você deve mapear
Zonereal (ouAlarmZonese você quiser) casos em seu relacionamento OneToMany vez de ids. Não há nenhuma necessidade de tabela intermediária, a menos que a relação é realmente ManyToMany caso em que devem ser mapeados como tal (pode uma única AlarmZone pertencer a mais de uma câmera? Se assim for, é de muitos para muitos). - Você tem anotação herança em sua entidade
Camera. Por quê? É parte de uma outra hierarquia? - O código "clichê" você está usando é ruim. Transação deve colocar um unidade inteira do trabalho , não entidade individual. rubor explícita é desnecessário.
mapeamento de amostra:
@Entity
@Inheritance(strategy = InheritanceType.JOINED)
@Table(name = "cameras")
public class Camera {
private long id;
private List<AlarmZone> alarm_zones = new ArrayList<AlarmZone>();
@SequenceGenerator(name="Camera_Gen", sequenceName="cameras_seq")
@Id @GeneratedValue(generator="Camera_Gen")
public long getId() {
return this.id;
}
@OneToMany(mappedBy="camera") // this maps a bi-directional relationship
public List<AlarmZone> getAlarmZones() {
return alarm_zones;
}
...
}
@Entity
@Inheritance(strategy = InheritanceType.JOINED)
@Table(name = "zones")
public class Zone {
// same deal as above
...
}
@Entity
@Table(name = "alarmzones")
public class AlarmZone extends Zone {
private Camera camera;
@ManyToOne
public Camera getCamera() {
return this.camera;
}
}
